ferpa-deid

Use for the de-identification / re-identification WORKFLOW — building the course-wide de-id master, de-identifying submissions or a gradebook (docx/pdf/xlsx/jupyter/databricks/text/comments) before anything reaches the LLM, re-identifying keyed results back to students, and scanning for name leaks. Load this when preparing student artifacts for AI processing or turning keyed results back into a named report. The FERPA *discipline* (never read Zone-2 files) is constitutional and always applies; this skill is the *how* of the de-id machinery.
